AUTOMATIC CORKSCREW.

SPECIFICATION forming part of Letters'latent No. 701,791, dated. J une3, 1902. Application filed January 14,V 1902. Serial No. 89.758. (Nomodel.)

To all whom, it' may concern,.-

Beit known that I, RANDALL B. ANDROS, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Automatic Cork--screws; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in automatic corkscrews; and theobject of the invention is to reduce to a minimum the fric! tion causedby compressing the knob of the handle and forcing a spiral worm into thecork of the bottle.

A further` object to be obtained is to automaticall y force the corkfrom the spiral worm' by means of a coiled spring after the with drawalof the cork.

With these ends in view the invention consists in the novel constructionand combination of parts, as will be hereinafter described, andparticularly pointed out in the claim.

In the accompanying drawings, to which reference is had and which fullyillustrate my invention,`Figure lis a front elevation of my device, andFig. 2 is a vertical sectional elevation of the same. p

Referring to the drawings, A designates the compression-knob or handle,Vhaving a recess d formed therein, within which is seated and securedthe upper end of a tube F. The upper part of this tube isscrew-threaded, as at d', in which engage screw threads formed, upon theperiphery of a screw-plug A', said screw plug having a hole madecentrally therethrough and a tubular shoulder a3 formed integraltherewith to receive revolubly the upper end of a spiral worm B, saidparts being located in the upper part of the tube F.

F designates another tube somewhat longer than the tube F and of lessdiameter which is arranged telescopically in relation to the tube F, thelower end of the tube being provided witha nut or solid portion F2 andhaving screw-threads cut therein to engage screwthreads formed upon thelower and inner portion of the tube F', this nut having also points c cintegral with or secured to the under side of the nut, which engage thecork and prevent the same from revolving, and it is'further providedwith a channel or passage-way formed centrally, as at f, through it,corresponding in` configuration to the spiral worm, which. is projectedand retracted through said channel in its operation.

B designates the spiral worm, provided at its upper end with a swivelB', which is formed vintegral with said worm and passed revolublythrough the hollow shoulder a3 and the screwplug A', to which it issecured and withinwhich it revolves.

D designates a coiled spring located in the tubing and surrounding thespiral worm, the upper end of said spring snugly and securely fittingaround the hollow shoulder a3 of the screw-plug A', the opposite andlower end of said spring being secured to the nut or solid portion F,2Within 4the tube F', upon which the handle C is secured, the securing ofthe spring to the shoulder of screw-plug A' and to the nut o'r solidportion withinthe tube being for the purpose of preventing the handleand its tube from becoming separated from the spiral worm, the tubing FandF' telescoping and serving as a casing for inclosing the mechanism.The worm is made of sheet-steel of the required width, and thepeculiarity of the worm or screw is that the pitch of 'the worm or screwis obtained by a twisting or rolling process. The object of the screw orworm is to reduce friction caused by the compression oi' the knobforcing the worm through the nut or solid portion of the handle into thecork.l The peculiar form of said worin reduces friction over theordinarily-constructed corkscrew, inasmuch as it permits the piercingofthe cork instantly.

The surrounding of the worm by the spring khas for its object to forcelthe handle to'traverse vertically the swivel worm or screw, which causesthe cork to be forced from the spiral worm or screw automaticallyafterjthe withdrawal of the cork. To extract the cork, the operatorsimply holds the ,compressionknob and handle together and draws in theordinary manner.

IOO

rounding the worm having its upper end secured to the tubular shoulderof the screwplug, the nut to which the lower end of the coiled spring issecured, a channel formed through said nut corresponding to the form ofthe worin, and points located on the under side of the nut,substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
